There's no way he personally contacted James or D'Arcy for the 2.0 reunion. It was only after his failed attempt to pass off Jeff and Ginger to the record execs that he had to reach out. Which was useless as the new band was already formed. I've always though this was the real motivation behind 2008 lawsuit, but I'm just guessing here

D'arcy even told two years ago that she got four offers to rejoin the band.
Some people made immediately a plea on this, that it was impossible, because he hadn't spoken with her since 1999.
But she said one of the things which upset her on Corgan the most was him using a policy to not connect with people directly, which she found disrespectful.

The first contact for rejoining the band was already for the last Metro show in 2000 according to her.
She also said that he made his record label executives for a long while believe that the 2007 reunion was with all four original members of the band.
Are there any reliable sources that he even got in trouble for it?

And when and for what reasons has he made his other offers?

Corgan telling he wants his Pumpkins music back still reads like written with self pity to me.
